ISAAC H. MILLIKEN,-OF ASPINWALL'PENNSYLVANIA, .ASSIGNOR 'TO THE McCONWAY 60 TORLEY COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

To all whom it may concern Bev it known that I, IsAAo H. IVIILL'IKEN, afcitizen of the United States, residing at Aspinwall, in the county of Allegheny and State of Pennsylvania, have invented cer tain new and useful Improvements in VVear Plates for Car-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same. i p

My invention relates to the construction ofwear plates for protecting the stems of car couplers from the wear to which they areordinarily subjected by sliding back and forth on'the supporting carry-iron when in service. The primary'object of the inven tion is to provide a device of the character indicated which may be detachably associated with the coupler in a manner permitting renewals and replacements to be readily made. A further object of the invention is to so construct the parts that the strength of the coupler will not be impaired and the wear plate may be associated with the coupler without interfering with any other parts of thecar equipment.

Generally stated, these objects are attained by providing the wear plate at one end with a plurality of lugs overlapping the V coupler stem and by forming it at the other with one or more recesses adapted to interfittingly engage correspondlng downwardly projecting lug or lugs on the coupler head,

the construction being such that the wear plate and coupler are interlocked in a manner restraining longitudinal and lateral movement of the plate with respect to the coupler when the device is in service.

In the drawings illustrating preferred embodiments of my invention, the scope whereof is pointed out in the claims,

Figure 1 is an inverted plan View of a car coupler and associated wear plate embodying the invention.

Fig. 2 is a side elevation of theconstruction shown in Fig. 1, a supporting carryiron being also illustrated.

Fig. 3 is an inverted plan View of a modified form of my invention.

Fig. 4: is a side elevation of the construction illustrated in Fig. 3, its supporting carry-iron being also shown.

Specification of Letters Patent.

Patented June 22, 1920.

Application filed March 21, 1918. Serial No. 223,770.

Fig. 5 is an inverted plan view of a further form of the invention. I i

Fig. 6 is a side elevation of the construction shown in Fig. 5, the coupler carry-iron being also illustrated. J p

In the drawings the head of the coupler is indicated at l and the coupler stem is indicated by the numeral 2,.while 3 is the carry-iron supporting the coupler and between which and the coupler the wear plate is interposed. Except for features specifically claimed herein, these members may be of any character desired. i

'In the construction illustrated inFigs. l and 2 the coupler is provided on its under side, preferably in a central position subs'tantially at the junction of the head 1 and stem 2, with a downwardly extending projection l that may be conveniently made of rectangular form, as shown. The neighboring end of the wear plate 5 is fashioned with a corresponding rectangular recess 6 which preferably closely embraces the projection 4, thus preventing the plate from shifting forwardly or laterally with respect to the coupler. At itsrear end the wear plate is preferablyprovided at each side with "aneupwardly projecting and rear-' wardly extending lug 7, the lugs 7 being spaced-apart laterally asuflicient distance to allow the stem 2 of the coupler to be received between them. These lugs 7 preferably not only engage the sides of the coupler stem to prevent lateral shifting of the rear end of the plate 5, but their rearwardly extending upper portions contact the upper surfaces of laterally projecting lugs 8 formed integral with the coupler stem, thereby serving to support the rear end of the plate 3. The engagement of the rear vertical faces of the lugs 7 with the forward faces of the lugs 8 prevent rearward shifting of the wear plate on the coupler, as will be readily apparent. 1

In the construction illustrated in Figs. 3 and 4 the wear plate 9 is provided at its forward end with a recess 10 of aform allowconnection is employed to maintainthe front end of the plate 9 in assembled relation to the coupler, the rear end of the plate may simply be provided with a pair of upwardly extending projections 11 which only engage the sides of the coupler stem 2, it being in such a case unnecessary to provide at that point any means for restraining longitudinal movement of the wear plate.

Figs. 5 and 6 illustrate a form of my invention in which the rear end of the wear plate 12 is provided with spaced upwardly extending lugs 11 engaging the sides of the coupler stem, as heretofore described; but the forward end of this plate 12 is provided with a lug 13 adapted to extend into a recess formed between a pair of spaced lugs 14 projecting downwardly from the under side of the coupler. The lug 13 is preferably of headed form, thus affording recesses 15 into which the respective lugs 14 fit. The interlitting engagement of the plate 12 and: lugs 14: not only prevents lateral movement of the forward end of the plate but also prevents longitudinal shifting of. the latter either forwardly or rearwardly with respect to the coupler.

The highest degree of efliciency issecured when the cooperating parts of the coupler and wear plate fit each other as snugly as possible, because movement of the wear plate relatively to the coupler is thus en-- tirely or almost entirely eliminated.

I claim:

1. In a device of the character indicated, the combinationwith a carry-iron, of a car coupler, and a wear plate interposed between said carry-iron and coupler and connected only to said coupler, said coupler and wear plate being provided with interfitting means for preventing lateral and longitudinal movements of said plate with respect to said coupler, said means involving a downwardly extending projection on said coupler adapted to engage said wear plate in advance of said carry-iron, and a plurality of spaced lugs formed on said Wear plate and embracing and engaging said coupler rearwardly of said carry-iron.

2. In a device of the character indicated, the combination with a car coupler having a downwardly extending projection, of a wear plate having at its forward end shouldered engagement with said projection, said coupler being provided rearwardly of said projection with a plurality of spaced lugs and said wear plate having a plurality of spaced lugs adapted respectively to engage the said spaced lugs of the coupler.

3. In a device of the character indicated, the combination with a car coupler having a lug on the under side thereof, of a wear plate connected to the coupler only and having at its forward end a recess adapted to receive said lug, said wear plate being provided at its rear end with a plurality of spaced lugs adapted to engage said coupler between them.

4. In a device of the character indicated, the combination with a car coupler, of a wear plate arranged beneath and secured only to said coupler and movable therewith, said coupler being provided with a plurality of lugs engaging the rear end of said plate a to prevent longitudinal movement of the latter with respect to said coupler, and the rear end of said wear plate being provided with a plurality of spaced lugs respectively adapted to engage said lugs upon said coupler.

In testimony whereof I affix my signature.

ISAAC H. MILLIKEN.
